灰色关联度在乒乓球各战术得失分率的应用——基于王楚钦第56届世界乒乓球锦标赛的数据

Application of Grey Relational Degree in Analyzing the Winning and Losing Points Rate of Table Tennis Tactics—Based on the Data of Wang Chuqin′s 56th World Table Tennis Championships

运用灰色关联度分析法,通过对王楚钦第56届世界乒乓球锦标赛中的7场比赛中各战术指标得失分率与总得失分率,从发抢段、接抢段和相持段的得失分来看,分析各战术形式指标的得失分比例。结果表明:王楚钦1、3拍得分率与总得分率的关联度最高;相持段失分率与总失分率关联度最高;发球抢攻战术得失分率与发抢段得失分率关联度最高;接发球战术得失分率与接抢段得失分率关联度最高;主动相持得分率与相持段得分率关联度最高;被动相持失分率与相持段失分率关联度最高。

Using the grey relational analysis method,this study analyzes the gain-loss ratios of various tactical indicators in the 56th World Table Tennis Championships'seven matches played by Wang Chuqin.By examining the gain-loss ratios in the serving-receiving phase,the receiving-serving phase,and the rally phase,the study analyzes the proportional gain-loss ratios of different tactical forms.The results indicate that Wang Chuqin's highest correlation is observed between the scoring rate on the 1st and 3rd shots and the overall scoring rate.The rally phase's loss rate shows the highest correlation with the overall loss rate.The gain-loss rate of the serve-attack tactic exhibits the highest correlation with the gain-loss rate in the serving-receiving phase.The gain-loss rate of the receive-serve tactic demonstrates the highest correlation with the gain-loss rate in the receiving-serving phase.The proactive scoring rate exhibits the highest correlation with the scoring rate in the rally phase.The passive loss rate demonstrates the highest correlation with the loss rate in the rally phase.
